TO ALL WHOM IT MAY CONCERN:

Be it known that I, CARLO MARGUTTI, of Milan, in the Kingdom of Italy, have invented a new andimproved Method of Railway-Locomotion; and I do hereby declare that the Following is a full, clear, and exact description thereof, whichjvill enable those skilled in the art to make and use the same, reference being had to the accom'- panying drawings .forming part of this specification.

This inventionrelates to a new and improved method ofconstructing locomotiveengines, and the tracks over which they run, and of increasing the friction or traction between the ehgine and the track for ascending inclined planes, and for passing around curves of short radii;

It consists in the construction, arrangement, and combination of the parts, as hereinafter specified.

In the accompanying plate of drawings- Figure 1 is a. plan view'of thy invention.

Figure 2 represents a central vertical longitudinal section ofthe same, taken in the line x x, tig. 1.

Figurel 3 represents a partial central cross-section ofthe same, taken in the line y gl, tig. i1.

Similar letters of reference indicate corresponding parts.

The frame A is'made ot'v like materials and in the same generalform as the frames of the trucks vof locomotive engines now commonly in use, and is lsupported by three pairs of wheels, C, rotating on the axles B.

Supported upon the frame A is a steam-engine, having the cylinders P ofthe same secured to the supports O in a horizontal position in the middle, and near each side ofthe frame A, as shown.

The piston-rods P pass entirely through the cylinder P at both ends of the same, and, extending beyond the cylinder P, are attached by each end of thesaidl piston-rod to the bars D.

The bars D are made of wood or metal, and extend nearly the entire length of the frameA above the axles B,and within the supports O, one on each side of and parallel with the frame A, as shown.

Said bars D are connected' together, at both ends of the same, by the chains G, one of said chains G being attached to each end of each of said bars by one end, and by the other end to the levers N, as shown, so that by rmoving one of said bars D horizontally in one direction, the other ofthe said bars will be moved in like manner in the opposite direction, said bars D resting upon and being supported by the axles B, as shown.

Under the 4axles B, and parallelAwit-h the bars D, are two other like bars, D', cach one of said bars D being in the same vertical linerwith one of the bars D.

The bars D are joined to the bars Dv by the bearings E, which are made in two segments, one ot' the segments of each bearing E being above, and the lother of said segments being below the axles B; said segments of each of said bearings E being held together by one of the pulleys F, in such a manner that when the centre of one of 'the bearings E on one side of the frame A is coincident with the centre of the axle B, within the same, the centres ofthe other bearings E will be coincident with the centres of the other axles B.

The benringsE are cylindrical in form, are three in number on each side, one upon cach end of each ofthe axles B within the frame A, and extend from said bars D and D inwardly, and are of suilcicnt length to receive the pnlleys'Fand theeccentrimscgments F,.as shown in the drawing,'the arrangement being such that a reciprocating rectilinear motion of the piston-rods P is thus communicated to the bearings E ou Oncside, moving in a direction opposite to that ot` the bearings E on the other side.

The pulleys F are made of iron or other suitable material, onc'npon cach of the bearings E, as shown, are equal in diameter, and are connected together by a cord or belt, R, passing over and around all the pulleys F on one sident" the frame A, and another like cord passingiover and around all the pulleys F on the other side ofthe frame A, in grooves in the circumference of said pulleys F, in such manner that when one of said pulleys Fis rotated upon one of the bearings E, all the pulleys F so connected together on the same side of the frame A will rotate in the same direction. e

Upon each side ofthe frame A, at either end of thc same, and rotating in 'suitable bearings, on uprights from said frame A, as shown in the drawing, is an endless screw, K, the same being in a' line parallel to the sides of the frame A.

` renti 2 Upon the pulley F on each side, at the same end of the frame as the endless screw K, and rigidly secured to said pulleys F, are the worm-wheels or segments of wheels L, said endless screw K fittinginto the teeth of Said worm-wheel, so that by giving arotating motion to the endless screw-K, a rotating motion is communicated to the worm -wheels L, and through the same to all' the pulleys F on one side of the frame A, all the pulleys F on one side of said frame A being rotated by onescrew K, andall the pulleys F ou the other side of the frame A being rotated by another screw K, the screw K also serving to hold the pulleys F firmly in any desired positionl on the bearings E.

The eocentriesegments F' are made 'of iron or other suitable material, are placed, one upon cach of the bearings E, are formed of n ring or band, by means of which the said pulleys F are held upon said bearings Fi, and a segment of a circle attached to a part of said band, so as to form a slot, a2, between said segment of a ,circle and said band, to recieve the guide al and spring a aroundV said vguide-rod al, as shown, the spring abeing secured to the face ofthe pulley F, the centre of said segment being as much one side of the bearings E as may be necessary, according te the elevation andrdepression in the rail M, hereinafter described.

The eccentric-segments F' rotate or partially rotate on the bearings E, beingstopped in the rotation of the same by the spring it. 4 v

The eccentric-segments F' are held against the wheels F by the metallic buttons c, pivoted to' the hub E E' at convenient points on the inner end of the same, as shown. v

The railroad is built upon any'grade less than the rise of about seventyiivc feet in heightjin the distance of one thousand feet, and may be built in curves of very short radii, my improvement ofthe same consisting in the addition of aeorrngated or waveshape?. rail,l M, between the two rails now commonly used.

IThe rail M is made ofiron or other suitable material, und is formed in alternate elevations cqnidistant from each other, 'as shown in the'y drawing, the distance from one elevation to another being in proper proportion to the dia-meter of the cocontric-segmentsv F', said rail M being of snliieient width on top to receive the eccentric segments F' on both sidesv ofthe middle of the frame A, as shown in the drawing.

The operation is such, thathy the reciprocating motion of the bearings E, the frame A. beingplaced over the outside rails of the track, with the wheels C upon the same, the eccentric-segments F' on one side of the frame A will be forced backwards against the inclined planes of the railM, and stopped from rotating by the spring c, the frame will be forced forwards, and the eccentric-segments F' on the. other side ofthe frame A being carried also forward by the bars D and D', will drop or be forced by the spring a into the depressions ofthe rail M, rotating snliicientlyin so doing asnot to be hindered in the forward movement of' the same by the elevations upon the rail M, so that it-isobviousthat the frameA will be forced forwardsat each backward movement ofthe piston P' by nll the eccentric-segments F', one side of the frame A acting against the elevations on the rail M, while all the scgmentsF' on the other side of the frame A, inthe forward movement of these-me, will partially rotate, so as not to hinder the forward motion ofthe saine, and will beforced back `to the` former position ofthe said eccentric-segments F' after the highest part of the elevation ofthe rail has been reached, when, by the revcrsemotion of the piston-rods P', the latter eccentric-segments F' will present the necessary resistance against the rail h'Lwhilc the former eccenltric-segments F' will partially rotate so as'not to be hindered in the forward movement of the same, the operation beingsimilar to that of a man walking, and by changing the eccentric-segments F' to the other side of the axles B by the endless screw K and pulleys F, a motion in'the opposite direction will be given to the frame A and the entire locomotive.

The eccentric-segments F' are so set with respect to each other. that one only of the same on each side will,

at the end of the forward movement of the same, rest at the lowest point ofthe depression of the rail M.

I claim as new, and desire to secure by Letters Patent l 1. A locomotive, provided with the eccentric-segments Ff', which act upon a corrugated or wave-shapedrail M, in the manner substantially as shown and described. I

2. Operating the eccentric-segments F' by means of the reciprocating bars D D' and the attached bearings E of the same, substantially as shown and described, and for the purposes set forth. l
